To allvwhom "it may concern:

Be it known that I, WILLIAM H. GILBERT, a citizen of the United States of America, residing at Lindsey, in the county of Sandusky and State of Ohio, have invented new and useful Improvements. in Belt-Clamps, ot' which the following is a specification.

rlhis invention is an improved belt clamp for connect-ing the ends of power transmission belts together and enabling such belts to be tightened, as may be required, without having to Iirst remove themv from the pulleys, and said invent-ion consists in the construetion, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawingir-Figure 1 is a plan view of a belt clamp embodying this invention, showing the same attached te the ends of the power transmission belt and connecting the same. Fig. 2 is a similar view, showing the opposite sides of the belt and of the clamp. Fig. 3 is an elevation at right angles to Fig. 1. Fig. 4 is a transverse sectional view taken on the plane indicated by the line 4-4 of Fig. 2.

In the construction of this improved belt cla-mp I employ a pair of heads or members 1, each of which comprises a cross arm 2 and a screw-threaded stein 3 which extends from the center thereof at right angles thereto. Such cross arm has its ends-.turned at right angles thereto, as at4. The screw-threaded stems of the respect-ive heads or members are oppositely threaded, one having a rightdiand thread and the other a left-hand thread, as shown. A turn buckle link 5, which is provided at its ends with oppositely threaded openings for the reception of the respective stems of the heads or members 1, serves to connect such heads or members together and :to adjust them longitudinally-toward or from each other, according to the direction in which such turn buckle link is tluned. In

connection with each of the arms 2 I provide a bar G, the length of which is such as to en- Specification of Letters Patent. ppncatineiea June 21, 1907. serial No. 389,141.

' arms and bars' on the .ends of such belt. I'Iaving thus attached the ends of the belt to the members of the clamp, it will be understood that the belt may be stretched or.- slackened, as may be required, by properly turning the turn buckle link 5.

A belt clamp as thus constructed is extremely cheap and simple, enables the ends of a belt to beheld in piace while a piece is being cut oif to shorten the belt, and while the ends are being secured together by means of lacing, rivets, belt hooks, clamps or the like devices, and, moreover, such belt clamp may be very readily attached to the ends of a belt or removed therefrom without the necessity of first removing the belt from the )ulleys which it connects.

I aving thus what is claimed as new, is:-

A belt clamp comprising a air of coacting clampingmembers, each em odying a cross arm raving a screw stem integral therewith and extending at right angles from the eenter of the outer face thereof, said cross arm being provided with upwardly bent ends, a clamping bar of a length t-o lie between the upwardly bent ends o? the cross arm and to clamp the inserted end of the belt against theV same, said upwardly bent ends of the cross arm engaging the ends of the bar and holdi ing the latter against movement laterally of the belt, bolts passing upward through the described the invention,

cross arm adjacent the upwardly bent ends thereof and also through the bar and adapted to bear against the edges of the belt to retain the same against lateral displacement, clamping nuts engaging the u per ends of the bolts and bearing on the Ear, the said screw stems of the clam )ing members being' oppositely threaded and arranged in alinement in the plane of t-he center of the ends of the belt engaged by the respective clamping members, and a turn buckle engaging said opposite screw threaded stems and c cnnecting such members together for longitudinal adjustment.

In testimony whereof, I aIix my signature 1.00

in presence of two witnesses,

IVILLIAM H. GILBERT.
